%X In this paper, a new bilateral registration measurement based on regional information and local frequency information is presented. Firstly, the original image is considered as the reference image and the forward regional mutual information as well as local frequency information is calculated. Meanwhile, the input image is regarded as the reference image and the corresponding backward information is obtained. Then, the forward and backward information is summed up and the residual information is subtracted from the summation to get the final bilateral similarity measurement that can be used for registration. Experimental results on real medical images indicate that the measurement is not sensitive to noise and low sampling resolution and can effectively improve medical image registration precision.
